Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:
Unicode C++

#include <CkXmlW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkXmlW xml;

    success = xml.LoadXmlFile(L"qa_data/xml/pigs.xml");
    if (success != true) {
        wprintf(L"%s\n",xml.lastErrorText());
        return;
    }

    //  Get the content of the "species" node for the 1st animal:
    const wchar_t *result = 0;
    result = xml.chilkatPath(L"animal|species|*");
    //  Output should be "pot belly pig"
    wprintf(L"%s\n",result);

    //  Get the content of the "type" node for the 2nd animal:
    //  Indexing begins at 0.  Therefore, the 2nd direct child having
    //  the tag "animal" is at index 1
    result = xml.chilkatPath(L"animal[1]|type|*");
    //  Output should be "House Pig"
    wprintf(L"%s\n",result);

    //  Find the pig having the name "Nigel" and display the
    //  birth date.  To do this, we&apos;ll navigate to the node having
    //  tag="name" with the exact content "Nigel", then navigate up, 
    //  and finally navigate back down to the "birth" node:
    result = xml.chilkatPath(L"/C/name,Nigel|..|birth|*");
    //  Output should be "June, 1991"
    wprintf(L"%s\n",result);

    //  Navigate to the 1st animal&apos;s picture and print the filename,
    //  description, and caption.
    //  The "$" updates the caller&apos;s internal pointer to reference
    //  the node that is the result of evaluating the path.
    //  An empty string is returned for success, and a NULL/nil/0
    //  pointer (reference) is returned on failure.  
    result = xml.chilkatPath(L"animal|picture|$");
    if (xml.get_LastMethodSuccess() != true) {
        wprintf(L"Failed to navigate to animal|picture.\n");
        return;
    }

    //  Display the contents of the file/description/caption child nodes
    wprintf(L"Picture Info:\n");
    wprintf(L"%s\n",xml.getChildContent(L"file"));
    wprintf(L"%s\n",xml.getChildContent(L"description"));
    wprintf(L"%s\n",xml.getChildContent(L"caption"));

    //  Return back to the root of the XML document:
    xml.GetRoot2();

    //  Display the value of the "spay-neuter" attribute of the 1st animal:
    wprintf(L"----\n");
    result = xml.chilkatPath(L"animal|gender|(spay-neuter)");
    wprintf(L"%s\n",result);
    }
